AIP-SSM-10 upgrade

I've got a customer who has 2 ASA's running each populated with AIP-SSM's. The IPS have 6.1(1) E3 software and I would like to upgrade them to the latest.

I'm searching through the download sections and have read the minimum requirements for 7.0(7) E4 but cannot find the file to download for AIP-SSM.

NOTE: The IPS-AIM-K9-7.0-7-E4.pkg upgrade file can only be used to
upgrade AIM-IPS sensors. The IPS-NME-K9-7.0-7-E4.pkg upgrade file can
only be used to upgrade NME-IPS sensors. For all other supported sensors,
use the IPS-K9-7.0-7-E4.pkg upgrade file.

Every upgrade image I look at for E4 only has IPS-K9-version and the description says all supported platforms except AIM-IPS and NME-IPS. Can someone help me locate the correct upgrade image?
